What to write about
- Corrections. If a figure looks wrong, send the page link, the number and why you think it's off. A link to a better source helps most.
- Data questions. Ask how a filter works or where a number comes from. The methodology page answers most of these, country by country.
- Press and media. You're welcome to quote the meter's numbers with a link to delulumeter.ai. Tell us the settings you used and we can check them for you.
- Partnerships and advertising. Tell us who you are and what you have in mind.
- Privacy requests. To ask what we hold or to have it deleted, see the privacy policy. We answer these within 30 days.
Before you write
We can't look up, contact or identify any individual man. The meter counts estimates from official statistics, not people, and has no profiles behind it.
